Mackworth is an island of approximately 100 acres connected to Falmouth by a causeway at the mouth of the Presumpscot River. This proximity to Portland and the Presumpscot accounts for the unique blend of human and natural history that has shaped Mackworth Island. While human influence has greatly altered the natural environment, there is much to be enjoyed and preserved. The trail that encircles the island takes about an hour to complete at a leisurely pace, and visitors are treated to stunning views of Casco Bay and Portland. Along the way, stop to watch boats and ferries motor through the Atlantic waters while seagulls, osprey, and shorebirds glide overhead as they search for food.
The island is open to visitors from 9:00 a.m. to dusk. There is an outhouse in the parking lot.
